Hi Robotics; I have been using the DFX for 4+ years now. I will put it up against any detector out there. I "routinely" find dimes at 10" - 12". I do it all the time. I even found a KG Large Cent at a "MEASURED 19". Yes, I have witnesses as well. Myv friend grabbed a tape measure from his car and we measured it because we couldn't believe it ourselves ok. It is a true turn on and go detector that will deliver the Depth and Accuracy. Get the Digging Deeper with the DFX Book and "MEMORIZE" it. Although you won't have to because you will have the new settings saved in your own Personalized Programs ok.
You can create several Programs and save them. Then no materr what you do you will have each Program specially created by yourself for each given type of detecting you will be doing. Also, yes I believe that either you just have not passed over any deeper coins or that you just did not understand the signals you were getting. If there is a coin and a pulltab side by side I will "KNOW" what the coin is and block out the pulltab. I can even do this in the Coin/ Jewelry Mode as well ok. It just takes PRACTICE, PRACTICE, PRACTICE.!!!
I don't think you mind doing that in this case lol. Anyways, Your in good hands here ok. Fletch88; Sorry you felt that way. HH. Me, I love it. PEACE:RONB
